FRANKLIN MILLER, OF ONAGA, KANSAS.

DOOR-HOLDER.

Application led November 13, 1909.

To all 'whom fit may concern.'

Be it known that I, FRANKLIN MILLER, a citizen of the United States,residing at Onaga, in the county of Pottawatomie and State of Kansas,have invented certain new and useful Improvements in Door-Holders, ofwhich the following is a specification.

My invention relates to clamps, and more especially to that class ofclamps now generally employed for the purpose of holding a door inperpendicular relation to the floor in order that said door may bejoined, the edges thereof planed, or for any other similar purpose.Heretofore, more or less difficulty has been encountered in producingdevices of this character at a low initial cost, and at the same timeproviding a clamp which shall be absolutely efficient.

It is an object of my invention, therefore, to overcome theseobjections, and to provide a clamp which, because of its few and simpleparts, is easily and quickly assembled and adjusted.

Another object of my invention is to produce a clamp provided withspecifically novel means for mounting the jaws of the device, said meanscomprising a resilient plate` suitably supported at its ends, the jawsbeing' carried centrally of this plate.

With the foregoing and other objects in view, my invention consists ofsuch details of construction and combination of parts as will behereinafter more fully described and specifically pointed out in theclaim.

In describing my invention in detail, reterence will be had to theaccompanying drawings in which like reference characters designate likeor corresponding parts throughout the several views, and in which-Figure l is a view in side elevation of my device, showing a door heldtherein. Fig. 2 is a top plan view of t-he resilient plate, and Fig. 3is a vertical sectional view of one of the jaws. Fig. 4 is a section onthe line 4 4 of Fig. 2.

In carrying my invention into practice, I provide an elongated resilientplate l, the ends of which are supported above the ioor by blocks 2 and3 having slots 4 and 5 therein, said slots forming seats for the ends ofsaid plate. These blocks are prevented from slipping by screws A whichfasten the plate to the blocks and which project slightly below thelatter, the ends A thereof forming floor-engaging spurs.

Specification of Letters Patent.

Patented June 21, 1910.

Serial No. 527,830.

Formed in the plate l and disposed nearer one end than the other, is alongitudinally extending slot 6, while upon the opposite side of thecenter of the plate and approximately in alinement with the slot is ascrewthreaded aperture 7. Jaws 8 and 9 are provided and have basesslightly broader than the resilient plate, their bases being providedwith channels 10 and l1 respectively, the sides of said channels beingadapted to engage the sides of the plate, whereby the tendency tolateral movement on the part of the jaws is overcome. A thumb-screw l2passes through the j aw 8 and is in screwthreaded engagement with theaperture 7.

The other jaw 9, has a similar screw l3 which projects through the slot6 and has a nut 14 upon its end, whereby the screw is tightened and thejaw rendered immovable.

From the foregoing' it is thought the operation olt my invention will bereadilyT understood, and its utility fully appreciated. It will be seenthat the immovable jaw is first liXed in position, the door then placedupon the plate and disposed adjacent said jaw, and finally theadjustable jaw is mounted uponithe plate and placed against the door,where it will be held by a tightening of the'thumb-screw. Any pressureor weight then applied to the door will cause the resilient plate to sagor bow downwardly, thus forcing the upper edges ot the clamps towardeach other and gripping the door more securely.

I desire it to be understood that slight changes in the construction andarrangement of parts within the scope of the claim hereunto appended maybe resorted to without deviating from the spirit of my invention.

My invention is also especially useful in holding window sash, and tableand counter tops, as well as large boards.

Vhat is claimed is:

A door holder comprising a pair of spaced blocks having aliningtransversely extending recesses in their Lipper faces, a horizontallydisposed resilient plate located with its ends in the recesses of theblocks, screws engaged through the plate and through the blocks, andextending slightly below the under surface of the blocks, said screwshaving sharpened points for engagement in a surface upon which theblocks are disposed to prevent slipping of the blocks, said plate havinga screw threaded opening therein and having a longitudinal slot locatedin spaced relation to the opening, said slot being at one side of thecenter of the plate and the opening being at the other side of thecenter of the plate, two jaws arranged for disposal upon the plate, eachof said jaws including a vertically extending face and a horizontallyextending face, said horizontally extending faces being of greater widththan the plate, and having longitudinally extending -recesses therein,and resultant side flanges, said jaws being disposed upon the plate withthe plate in their recesses and with their side tianges against the sideedges of the plates, a screw engaged through one of the jaws and in thescrew threaded opening of the plate, a screw engaged through the otherjaw and through the longitudinal slot of the plate, and a clamping nutengaged with the lower end of the last named screw and resting againstthe undersurface of the plate.

In testimony whereof I aflixmy signature, in presence of two witnesses.

FRANKLIN MILLER.
